Map sequence for the most recent 40 days. First panel shows the OLR total
field. Second panel shows the OLR anomalies with respect to the climatological
mean and seasonal cycle (base period 1979 to 1995). Third panel shows the
OLR anomalies created by removing the 40-day mean (of this sequence). Fourth
panel shows the sum of the anomalies attributed to the MJO, Kelvin wave,
n = 1 equatorial Rossby wave, and mixed Rossby-gravity wave as
presented in the next plot, accessible by clicking
